She added that she'd love the chance to work with Monteith again soon.

"He loves singing," she dished. "And I'd love to sing with him one day, because he's got a great voice."

When she spoke to us about it earlier this year, Gomez said she was "thrilled" about the film, which revolves around three friends who go to Monte Carlo after one of them is mistaken for a British heiress, and revealed a bit about what fans can expect from her character.

"I play Grace. She's from Texas, and she's a girl who saved up money to go to Paris for the summer with her best friend," she said of the flick, which also stars Katie Cassidy. "And lots of drama goes on, and it's fun."
